Abstract :
For high resolution positron emission tomographs based on scintillation detectors a fast, dense and bright scintillator is required. An early sample of a new scintillator, Lu0.8Y0.2AlO3:Ce (LuYAP) with a density of 7.7g/cm3 and a scintillation decay time of 20 ns and 160 ns is compared with LSO and BGO crystals of the same size to estimate the potential of the crystal for high resolution PET detectors. Special attention was paid to use an application specific measurement setup with respect to high resolution positron emission tomography.
